Abstract

PROBLEM TO BE SOLVED: To allow a communication unit provided with a plurality of radio transmission sections to suppress production of spurious radio waves due to intermodulation without making the entire unit large in size and heavy in weight. SOLUTION: In the case that the communication unit receives a UI (RT = paging, MM=-, CC=-) from a radio base station while a transmission means of a PHSRF section 6 is in operation and its ID matches an ID of its own station, the communication unit rejects processing for a request of 'PDC incoming call' attended with the UI signal and does not make transmission by a PDC transmission means. Thus, simultaneous transmission by using the PDC transmission means and the PHS transmission means is not caused, resulting that the quality of a transmission radio wave from the PHS transmission means is kept high.

And the EEPROM 19 constitute a PDC / PHS combined type mobile phone.

The PDC / P constructed as described above
By subscribing to a mobile phone (PDC) service, the HS complex type mobile phone is given a mobile phone number, and information necessary for connection is stored in the EEPROM 19.
Accordingly, actual communication via a PDC wireless base station (hereinafter, this communication method is referred to as “mobile”) has become possible, and by subscribing to a PHS public network service, a PHS telephone A number is given and information necessary for connection is stored in the EEPROM 19, so that actual communication via the PHS radio base station (hereinafter, this communication method is referred to as "PHS") is enabled. By registering with the private PHS exchange, the extension number is given and the information necessary for connection is EEPRO.
M19, so that actual communication via the private PHS exchange (hereinafter, this communication method is referred to as “OS (office station)”) is enabled. An extension number is given by registering with the handset, and information necessary for connection is stored in the EEPROM 19, and accordingly, actual communication via the digital cordless telephone base unit (hereinafter, this communication method is referred to as "PHS (Home Station) ”).

In the "PHS", in addition to the above, P
There is also a communication system that enables the use of “PHS” inside a room through a home antenna having a repeater function installed indoors in the service area of the HS radio base station. Description is omitted.

Hereinafter, the PDC / P constructed as described above will be described.
First, the operation of the "mobile phone" of the HS complex type mobile phone will be described by dividing the operation into "standby", "incoming call", "communication", and "outgoing call".

[Standby] When the power is turned on, the microcomputer 13 reads the subscriber number (MSN), the mobile station number (MSI), the perch channel number, etc. from the EEPROM 19, and measures the reception levels of the frequencies corresponding to all the perch channel numbers. Then, a table is created in the order of the reception level and stored in the RAM of the storage unit 18. Then, first, the frequency is switched to the highest level to establish synchronization (frame synchronization and superframe synchronization) by the channel codec of the PDC baseband unit 5 and the microcomputer 13, and then the broadcast information from the base station is transmitted to the microcomputer 13. Reads and checks the standby conditions and the like, and shifts to the standby channel specified by the broadcast information.

If the synchronization is not established or the standby condition is not satisfied, the above-mentioned operation is repeated by switching to the next frequency based on the level order table stored in the RAM of the storage unit 18.

During standby, the channel codec of the PDC baseband unit 5 intermittently receives the PCH (paging channel) on the common control channel, and during standby, it is instructed by its own station and the broadcast information. The electric field strength of the peripheral channel is intermittently measured by the receiving means of the PDCRF unit 4.

[Incoming Call] The PDC radio base station transmits incoming call information on the PCH to the calling mobile station. The mobile station receives the incoming information on the PCH every time by the channel codec of the PDC baseband unit 5, and the microcomputer 13
As a result of the information analysis, if the incoming information is addressed to the own station, the microcomputer 13 controls the voice codec 8 to output a ring tone to the buzzer 12 or vibrate the vibrator 16 and blink the incoming LED 15.

At this time, a radio status report including the electric field strengths of the local station and the peripheral channels is transmitted to the PDC radio base station, and thereafter, the microcomputer 13 transmits the PDC signal to the PDC baseband unit 5 via the channel codec of the PDC baseband unit 5. By exchanging messages with the radio base station, a communication channel is set in accordance with the digital car telephone system standard.

[Communication] In the communication channel, either voice communication or data communication is performed. In the case of voice communication, reception is performed by the antenna 1 or 2.
(Switching by diversity) and receive PDC
A signal from the RF unit 4 is output to the receiver 9 or the earphone microphone jack 11 via the PDC baseband unit 5 and the audio codec 8, and the audio input from the microphone 10 or the earphone microphone jack 11 is output to the audio codec 8 and the PDC The radio wave is transmitted from the antenna 2 via the baseband unit 5 and the PDCRF unit 4.

On the other hand, during data communication, transmission and reception of radio waves are performed in the same manner as in the above-described voice communication.
A signal from the C baseband unit 5 is output to an external interface connector via an interface circuit (not shown), and data communication is performed by an external device connected to the external interface connector.

[Origination] While the mobile station is waiting, the input unit 1
When the transmission operation is performed by the key operation of 7 or the like, the microcomputer 13 generates a message including the other party number and the peripheral electric field strength, and transmits the radio wave from the antenna 2 through the channel codec of the PDC baseband unit 5 and the PDCRF unit 4. P
While transmitting to the DC radio base station,
Exchanges messages with the PDC wireless base station via the channel codec of the PDC baseband unit 5, thereby setting a communication channel in accordance with the digital mobile phone system standard.

The above is the operation of “mobile”, and then “P”
The operation of the “HS” will be described separately for “standby (intermittent reception)”, “incoming call”, and “outgoing call”. Note that the [communication] is the same as the above-described "mobile" operation, and therefore will not be described. Also, the mobile station is set to “PS” so as not to be confused with the operation of the “mobile” described above.
(Personal Station), base station "CS" (Cell Stati
on) will be described below.

[Standby (intermittent reception)] When the power is turned on, the microcomputer 13 reads the CS-ID from the EEPROM 19
(CS identification code) and PS-ID (PS identification code) are read and supplied to the PHS baseband unit 7, and then the PHS
The baseband unit 7 receives, via the antenna 2 and the PHSRF unit 6, a broadcast channel on which the CS is performing intermittent transmission, and a CS-I in the received broadcast channel.
The microcomputer 13 compares D with the CS-ID read from the EEPROM 19, and when the CS-ID matches, the PS validates the information in the broadcast channel.

Similarly, the CS also receives the paging channel on which the CS is performing intermittent transmission, compares the CS-IDs, and when they match, validates the information of this channel and shifts to the intermittent reception operation. During the intermittent reception operation, the intensity of the radio wave coming from the CS is measured by the receiving means of the PHSRF unit 6.

[Incoming Call] In the intermittent transmission of CS, if there is an incoming call during the intermittent reception of PS, the CS carries the incoming call information on the paging channel in order to notify the PS of the incoming call (similar to the intermittent transmission). Steps). When the PS receives the paging channel containing the incoming call information, the microcomputer 13 controls the voice codec 8 to output the incoming call sound to the buzzer 12 or vibrates the vibrator 16 and blinks the incoming call LED 15 to ring the incoming call. After that, the connection confirmation information is returned to the CS through the dedicated cell channel.

[Transmission] In the intermittent transmission of the CS, when the transmission operation is performed by the key operation of the input unit 17 of the PS during the intermittent reception of the PS, the microcomputer 13 causes the baseband unit 7 and the PH to operate.
Using the SRF unit 6, the control carrier transmits a link channel establishment request to the CS using the dedicated cell channel. Then, the CS receiving this performs, for example, carrier sense of a communication carrier selected at random, and returns a link channel assignment with a control carrier to the PS if the slot of the carrier is not used, and switches to the assigned carrier. Wait for a sync burst.

On the other hand, the PS that has received the link channel assignment switches to the assigned communication carrier, performs a carrier sense, and transmits a synchronization burst. Thereafter, the PS uses the communication channel according to the second generation digital cordless telephone system standard. Set.

The above is the operation of the “PHS”, and the “OS”
And detailed description of the operation of “HS” is omitted. Next, the operation of the state transition processing is described with reference to FIGS.

In a state where the data of the state transition is stored in the storage unit 18, the user,
When a request is generated from the base station or the device main body, the microcomputer 13 stores the request in the storage unit 18 and executes a request process shown in FIG. 6. When the request process is started, The microcomputer 13 retrieves the current state and request stored in the storage unit 18 from the storage unit 18 (steps S1 and S2), and retrieves and executes processing corresponding to the retrieved state and request from the storage unit 18. Along with (Step S3), the state symbol to be transited is taken out from the storage unit 18 and written as the current state in the storage unit 18 (Step S4), and then the executed request is deleted from the storage unit 18 (Step S6). If the process based on the current state and the request is "rejected" and there is received information, the received information is stored or reported (step S5).

Therefore, for example, as shown in FIG. 3A, in the state where “A: standby” is stored in the storage unit 18 as the current state, the P
When the incoming call is notified from the DC radio base station and the paging signal is addressed to the own station, "6: PD
A request for “C incoming” is generated and stored in the storage unit 18, and the request process shown in FIG. 6 is executed.

As shown in FIG. 7 (a), this paging signal is composed of "message type", "BCCH reception section length", "number of called mobile stations", "number of called mobile stations", "mobile station number", "received call number". ID number "and" Caller information "
Of these, paging is determined by the “message type”, the number of mobile stations (one in this case) is determined by the “number of mobile stations”, and the MSI of the mobile station receiving the incoming call is determined by the “mobile station number” (this When the MSI matches the MSI of the own station, it is determined that the call is received.) The management number temporarily assigned on the network by the “call identification number” is “caller information”.
Thus, information such as the telephone number of the caller can be recognized. In addition, the “sender information” is shown in FIG.
As shown in (b), for example, it can be obtained by 49 bits of information for 7 bits and 7 words. As described above, the reason for using 7 bits and 7 words and 49 bits of information is that at least one bit is required for transmitting a normal 11-digit telephone number.
This is because it is assumed that 4 bits per digit, that is, a total of 44 bits or more are required, and the present invention is not limited to this.

Then, according to the request process shown in FIG. 6, "A: standby" and "6: PDC incoming" are extracted as the current state and the request, and P is determined as the process corresponding to "A-6".
The DC incoming flow is performed, and “I: PDC communication in progress” is written in the storage unit 18 as the current state based on the state transition data stored in the storage unit 18, and then “6: PDC incoming” The request is deleted from the storage unit 18 and becomes data as shown in FIG.

Note that this PDC incoming flow is based on the control sequence shown in FIG. 8, from the UI (incoming radio status report,-,-) transmitted from the mobile communication device to the base station, from the mobile communication device to the base station. Up to SB4 to be transmitted, during this time, the UI (incoming radio status report,-,-) from the mobile communication device to the base station responds to the incoming message by transmitting the incoming radio status report, and (-, Authentication request,-) transmitted to the base station and the UI (-, authentication response,-) transmitted from the mobile communication device to the base station authenticate that the mobile station is a legitimate mobile station. Measuring and reporting the level of the radio wave intensity by the UI (level measurement request,-,-) transmitted to the mobile communication device and the UI (level measurement response,-,-) transmitted from the mobile communication device to the base station; Then the base Designates a radio channel while transmitting SB1 on the communication channel, and upon receiving the signal, the mobile communication device switches the frequency to the designated radio channel, transmits SB2 in synchronization with the previous SB1, and transmits a signal to the base station. And SB3,
SB4 is exchanged to acquire synchronization on the communication channel, and I (-,-, call setting) transmitted from the base station to the mobile station, and transmitted from the mobile station to the base station. I (-,-, call) and I (-,-, response), and I (-,-, response confirmation) transmitted from the base station to the mobile station
Are executed in the process during communication.

Further, in the explanatory diagram showing the state transitions shown in FIG. 4, the state transitions of [rejection of request and storage of information], [waiting for primary hold of request], and [rejection of request expected to be retried] are respectively shown. These state transitions will be described below.

[Rejection of Request and Storage of Information]
C, D, and E receive the request of “6: PDC termination” because the transmitting means of the PHSRF unit 6 is operating, ie,
As described above, the UI (RT = paging,
Even if the MM =-, CC =-) signal is received and matches the ID of the own station, transmission in response to this signal must not be performed.

Therefore, “B: PHS location registration”, “D: P
"HS location registration / PDC transmission waiting""E: PHS communication in progress"
In the state (2), the processing for the request of "6: PDC incoming" (step S3 in FIG. 6) is "rejected" (processing contents of B-6, C-6, D-6, and E-6 in FIG. 5). , PDC
The caller information stored in the paging signal and the fact that there is an incoming call are stored, and the current state is maintained without state transition (B-6, C-6, D-6, and E- in FIG. 4). 6 state transition). Then, based on the stored information, the display unit 14
Or the user can be notified by generating a notification sound with the audio codec 8 and outputting it from the receiver 9, and by displaying information such as a telephone number in the incoming call information, this is displayed. It is possible to tell who received the call.

As a result, the transmission by the PDC transmitting means (processing from the UI (incoming radio status report,-,-) in FIG. 8) is not performed, so that the PDC transmitting means and the PHS transmitting means transmit simultaneously. Therefore, the transmission radio wave can be maintained at a high quality.

The states F, G, H, and I are the PDCRF units 4
In the case where a request for “3: PHS incoming call” is received, the processing for the request is “rejected” as described above (F-3 and G-3 in FIG. 5). , H-
3, the processing contents of I-3), the fact that there is an incoming call via PHS is stored, and the current state is maintained without state transition (F-3, G-3, H-3, and F-3 in FIG. 4). I-3 state transition), so that transmission by the PHS communication means is not performed.

When "E: PHS communication is in progress", "5: PDC
In the case where there is a request for "calling" or when there is a request for "2: PHS calling" in "I: PDC communication", the processing for the request is "rejected" as described above, and this is the user. In this case, the user is notified of the unusable state, the current state is maintained without state transition, and the PHS transmission unit and the PDC transmission unit are not simultaneously transmitted.

[Waiting for Primary Suspension of Request] In this process, the state changes along the route shown by the arrow in FIG.
There are two types, a solid line and a chain line. Here, the solid arrow will be described.

When the request of “5: PDC transmission” is received in the state of “B: PHS location registration”, that is, when the user operates the input unit 17 to perform the PDC transmission operation, the PHS transmission is performed. Since the means is in operation, P
Although transmission using DC cannot be performed, if this request is rejected, the user operates the input unit 17 again to input P
A calling operation by DC must be performed. But,
The transmission of the PHS location registration is completed in a short time, and the PDC
Since the transmission means can be used, by transmitting the PDC after the PHS location registration, the user does not need to perform the retransmission operation.

Accordingly, "D: PHS location registration / waiting for PDC transmission" is provided as the current state to wait for the completion of PHS location registration, and "D: P" for "B-5".
The state transits to the state of "HS location registration / PDC transmission waiting", and then the PHS location registration is completed in the state of "D: PHS location registration / PDC transmission waiting", and a request of "7: PHS location registration end" is generated. At this time, PDC transmission processing is executed, the state is changed to “I: PDC communication in progress”, and the state shifts to PDC communication.

As a result, during transmission by the PHS transmission means, transmission by the PDC transmission means is not performed.
Since the DC transmitting means and the PHS transmitting means do not transmit at the same time, the transmission radio wave can be maintained at high quality, and the retransmission operation by the user can be made unnecessary.

Similarly, “G: PDC location registration / PHS transmission waiting” is provided as the current state, and PHS transmission during PDC location registration is performed through “F-2” and “G-9” and then “E”. : PHS communication in progress ”.

[Rejection of Request for Expected Retry] When periodic location registration is set, the communication device has a timer and periodically performs location registration. When it is time to perform location registration by the dynamic location registration, a request for “4: PDC location registration” is generated inside the communication device, and at this time, the state in which the PHS transmission means is operating (B, C, D, In E), the PDC location registration process is rejected, but the location registration is specified to be performed periodically. For example, a location registration request is generated every 100 seconds. There is no particular need to memorize and report the rejection since retry is performed periodically.

As a result, during transmission by the PHS transmission means, transmission by the PDC transmission means is not performed.
Since the DC transmission means and the PHS transmission means do not transmit at the same time, the transmission radio wave can be maintained at a high quality, and the standby state is not unnecessarily maintained.

The same applies to the case where the PDC is transmitting (F, G, H, I) in response to the periodic position registration request of the PHS.

The above-mentioned [rejection of request and storage of information]
In the case of the request of “6: PDC reception” in the state of “B: PHS registration” or the request of “3: PHS reception” in the state of “F: PDC registration”, Depending on the system of the base station, the arrival of PDC or PHS may be notified several times, and even if the incoming call processing is refused, retry is substantially performed, and PHS registration or PDC registration has been completed by then. In some cases, the status may shift to B, A, I or F, A, E, and it is possible to answer the incoming call. May be.

As described above, according to the present embodiment, high-quality transmission radio waves can be maintained by controlling the PDC transmitting means and the PHS transmitting means not to transmit at the same time in state transition. it can.

In the present embodiment, the above-described operation control is executed based on programs and data stored in the storage unit 18 in advance. However, the present invention is not limited to this. Is read from a recording medium or received through a wireless line and stored in the storage unit 18,
